| Rezumat | ||||||
Every natural class of left R-modules is closed, i.e. is completely described
by special set of left ideals of R (natural set). Some characterizations of such sets are
shown. The complementation operator of sets is defined and its properties permit to
transfer some results on natural classes to the lattice of left ideals of R. |
